Hedgehogs are generally insectivorous and their diet should primarily consist of high-quality cat food, insects, and some fruits in moderation. However, there are certain fruits that can be toxic or harmful to hedgehogs. Here’s a list of fruits you should avoid:

1. **Grapes and Raisins**: These can cause kidney failure in many animals, including hedgehogs. It's best to avoid them entirely.

2. **Citrus Fruits**: Fruits like oranges, lemons, and limes can upset a hedgehog's stomach and lead to digestive issues. The acidity can be harmful.

3. **Avocado**: This fruit contains persin, which can be toxic to many animals, including hedgehogs. It can cause respiratory distress and fluid accumulation.

4. **Cherries**: The pits of cherries contain cyanide, which is toxic. Even though the flesh is not harmful, it’s better to avoid them altogether.

5. **Peaches and Plums**: Similar to cherries, the pits of these fruits can be dangerous due to cyanide content.

6. **Tomatoes**: While technically a fruit, unripe tomatoes and the leaves can be toxic due to solanine.

When introducing any new food, including fruits, always do so gradually and monitor your hedgehog for any adverse reactions. Stick to safe fruits like apples (without seeds), bananas, and blueberries in moderation. Always consult with a vet if you're unsure about what to feed your hedgehog.
